Abstract

The utility model discloses an artificial closed cardiac massager, comprising a board of 60x40x2cm. Two sulciform metal pushing pedestals are fixed on the board, the distance between which is 46 cm, and two metal cannula with bottom in the shape of reversed T are pushed into the pedestals. Two hoisting metal tubes with the top end being like a ''U'' shape are inserted respectively into the two cannulas, with the U shape end of one cannula smaller and the other larger. Two metal hoisting tubes are both graduated and are adjusted in height by two screws. One end of a square metal lever is connected with the metal tube with smaller ''U'' top end through a revolving axis. A sliding pressure pad of silica gel is arranged on the square lever, and pressing downward of the lever will make the pressure pad press on the juncture of middle and inferior segments of the breast bone so as to produce closed cardiac massage. The closed cardiac massager in the utility model is low in cost, simple and practical, easy to operate, labor-saving, certain in pressing effect, with fewer complications and easy for generalization.

Description

Artificial outer chest heart pressing device

Technical field: the present invention designs a kind of medical apparatus; specifically; it is the outer chest heart pressing device when carrying out cardio-pulmonary resuscitation when being used for sudden cardiac arrest or sudden cardiac death; cause thoracic cavity malleation and negative pressure alternate by pushing patient's thorax; thereby make outside intrathoracic heart, blood vessel and the thoracic cavity and form pressure reduction between the artery and vein, promptly so-called " breast pump mechanism " promotes blood circulation.

Background technology: sudden cardiac arrest is meant that emergent mechanical activity stops, sudden cardiac death be meant acute symptom show effect take place in back 1 hour with consciousness suddenly forfeiture be natural death feature, that cause by the heart reason, sudden cardiac death takes place in annual about 300,000 people of the U.S., account for more than 50% of whole cardiovascular death numbers, and be 20～60 years old male's the first cause of the death, China's sudden cardiac death incidence rate is estimated to account for about 5% of total death toll, and in rising trend.In case sudden cardiac arrest or sudden death take place, capable immediately external chest compression, setting up effectively, circulation is the key of successful rescue.Traditional artificial closed cardiac massage is because of operating technology, the dynamics of pushing, and the size of the anteroposterior diameter of patient's thorax and the factors such as physical situation of rescuer are difficult to reach the ideal effect of pushing more.And complication is many, therefore, develop easy to operate, push effectively, depressor that complication is few, have great importance.

Summary of the invention: the purpose of this invention is to provide a kind ofly when being applicable to sudden cardiac arrest or cardiac sudden death, carry out the utensil of closed cardiac massage.This depressor consists of the following components: the plank of (1) 1 60 * 40 * 2cm, two flute profile metabs at a distance of 46cm on (2) plank, base internal diameter 2.7cm, external diameter 3.3cm, height 0.3cm, (3) two high 15cm of metal canula, internal diameter 2.0cm, external diameter 2.5cm, (4) two long 3cm of control screw, diameter 1.3cm, (5) two upper ends are " U " shape lifting metal tube, wherein a upper end is little " U " shape, and another root upper end is big " U " shape, diameter 2cm, long 20cm, every 0.5cm down scale is arranged on it, the long scale of 1cm, 1 of (6) rotating shaft, diameter 1.0cm, (7) square metal tube is provided with slidably silica gel pressure pad, 5 * 5cm, (8) square metal tube 2 * 2cm, long 60cm, (9) wooden handle, long 10cm, diameter 4.0cm.This depressor is cheap, simple and practical, and easy operating is laborsaving, pushes definite effect, and complication is few, is easy to promote the use of.

Description of drawings: Figure of description 1 is structural representation of the present invention with accompanying drawing 2, and Fig. 1 is a front elevation, and Fig. 2 is a side view.

The specific embodiment: according to Fig. 1 and Fig. 2, feature of the present invention comprises: the plank of (1) 1 60 * 40 * 2cm, two flute profile metabs at a distance of 46cm on (2) plank, base internal diameter 2.7cm, external diameter 3.3cm, height 0.3cm, (3) two high 15cm of metal canula, internal diameter 2.0cm, external diameter 2.5cm, (4) two long 3cm of control screw, diameter 1.3cm, (5) two upper ends are " U " shape lifting metal tube, and wherein a upper end is little " U " shape, another root upper end is big " U " shape, diameter 2cm, long 20cm has down scale every 0.5cm on it, the long scale of 1cm, (6) rotating shaft is 1, diameter 1.0cm, and (7) square metal tube is provided with slidably silica gel pressure pad, 5 * 5cm, (8) square metal tube 2 * 2cm, long 60cm, (9) wooden handle, long 10cm, diameter 4.0cm.

When using this depressor, allow patient take dorsal position earlier, the plank pad in patients back, is exposed the shirtfront, press shown in the accompanying drawing, install, it is identical with the patient's chest height to regulate the both sides height, and the silica gel pressure pad is aimed at following 1/3 intersection in patient's breastbone, and the handle of holding with a firm grip then presses down, make the breastbone amplitude of moving down reach 4～5cm, lift rapidly then, the time that presses down and lift respectively accounts for 50%, compression frequency per minute 80～100 times, use this depressor to push efficiency index to be: patient's lip changes red, pupil touches large artery trunks and beats by dwindling greatly, and systolic pressure reaches more than the 60mmHg, muscular tension increases, and autonomous respiration recovers.

Claims

The artificial outer chest heart pressing device of the present invention is characterized in that: the plank of (1) 1 60 * 40 * 2cm, two flute profile metabs at a distance of 46cm on (2) plank, base internal diameter 2.7cm, external diameter 3.3cm, height 0.3cm, (3) two high 15cm of metal canula, internal diameter 2.0cm, external diameter 2.5cm, (4) two long 3cm of control screw, diameter 1.3cm, (5) two upper ends are " U " shape lifting metal tube, and wherein a upper end is little " U " shape, another root upper end is big " U " shape, diameter 2cm, long 20cm has down scale every 0.5cm on it, the long scale of 1cm, (6) rotating shaft is 1, diameter 1.0cm, and (7) square metal tube is provided with slidably silica gel pressure pad, 5 * 5cm, (8) square metal tube 2 * 2cm, long 60cm, (9) wooden handle, long 10cm, diameter 4.0cm.
